Application of Carbon Nanoparticles in Da Vinci Radical Resection of Rectal Carcinoma

Objective To summarize the application of carbon nanoparticles in Da Vinci radical resection of rectal carcinoma.

Methods We collected and analyzed the clinical data of 11 rectal cancer patients who underwent Da Vinci total mesorectal excision(TME) with carbon nanoparticles injection before operation in our hospital from July 2017 to December 2017.

Results All operations went smoothly without abdominal incision, and three of them received ileostomy.The operation time was (184.6±23.5)ml, the amount of bleeding was (30.9±7.6)ml, and the length of removal intestinal canal was (18.8±2.1)cm.The number of dissected lymph node was (17.5±1.9), among them there were (3.4±1.5) of lymphatic metastasis and (7.5±1.4) of tiny lymph node.The length of lower incisal margin was (2.8±0.4)cm.There was no tumor tissue in broken end or circumferential resection margin of specimens, all were conformed to total mesorectal excision.The exhaust time was (25.9±7.4)h, the fasting time was (12.7±3.1)h and the length of stay after operation was (6.6±0.7)d.There was no bleeding, infection, intestinal fistula or intestinal obstruction.There was no relapse or metastasis in 1-6 months of follow-up.

Conclusion  Carbon nanoparticles are safe and convenient in Da Vinci total mesorectal excision, and they are helpful for lymphadenectomy especially to tiny lymph node.
